- 1 tablespoon Dijon mustard: Injects a subtle but distinct tang that lifts the whole dish.

- ½ teaspoon onion powder: Adds mild sweetness and complexity.
- Salt and pepper to taste: Essential seasonings to bring out all the delicious flavors.
- 1 cup crushed Ritz crackers (about 1 sleeve): Creates a crunchy, buttery topping that’s pure perfection.

How to Make Chicken Cordon Bleu Casserole Recipe
Step 1: Prepare the Baking Dish
Begin by preheating your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish. This simple step ensures your casserole won’t stick and will brown evenly while baking.
Step 2: Combine the Main Ingredients
In a large mixing bowl, toss together the cooked chicken, diced ham, and 1 ½ cups of the shredded Swiss cheese. This trio is the heart of your casserole, promising tons of savory flavor in every forkful.
Step 3: Whisk the Creamy Sauce
In a separate bowl, whisk the cream of chicken soup, sour cream, Dijon mustard, garlic powder, onion powder, salt, and pepper until smooth. This sauce is the magic that binds your casserole, infusing each bite with rich and tangy notes.
Step 4: Combine and Spread
Pour the creamy mixture over the chicken and ham, folding everything together so it’s thoroughly coated. Then spread this delicious mixture evenly into your prepared baking dish, creating an inviting layer just waiting to be baked.
Step 5: Add Cheese and Topping
Sprinkle the remaining ½ cup of Swiss cheese evenly over the top of the casserole for an extra cheesy finish. Next, mix the crushed Ritz crackers with melted butter in a small bowl to create a buttery, crispy crust, then sprinkle it over the cheese layer. This topping makes every bite exciting and adds a beautiful golden color.
Step 6: Bake to Perfection
Bake the casserole uncovered for 30 to 35 minutes, or until it’s bubbly and the cracker topping turns a gorgeous golden brown. Once out of the oven, let it rest for 5 minutes to allow the flavors to meld and the casserole to set slightly for perfect slicing.
How to Serve Chicken Cordon Bleu Casserole Recipe

Garnishes
A sprinkle of fresh chopped parsley not only livens up the flavors but brings a delightful pop of green that makes your dish look as good as it tastes. Feel free to add a few thin lemon slices on the side to brighten each bite with a hint of citrus.
Side Dishes
This Chicken Cordon Bleu Casserole Recipe pairs beautifully with light, fresh sides such as steamed green beans or a crisp mixed greens salad dressed with a lemon vinaigrette. These choices balance the richness of the casserole and make the meal well-rounded and satisfying.
Creative Ways to Present
For a more elegant presentation at gatherings, serve the casserole in individual ramekins or mini cast-iron skillets. You can also scoop the casserole atop buttered egg noodles or fluffy mashed potatoes for an indulgent twist that turns it into a full-blown feast.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors often deepen overnight, making it just as tasty the next day, if not better. Covering the casserole well keeps the topping from getting soggy.
Freezing
This Chicken Cordon Bleu Casserole Recipe freezes wonderfully. Assemble the casserole in a freezer-safe dish, cover tightly with foil or plastic wrap, and freeze for up to three months. When ready to enjoy, thaw overnight in the fridge before baking.
Reheating
To reheat, place individual portions or the whole casserole in a preheated oven at 325°F (160°C) until warmed through and the topping crisps up again, usually about 20 to 25 minutes. Avoid microwaving if you want to keep the deliciously crunchy topping intact.
FAQs
Can I use fresh chicken instead of cooked chicken?
You definitely can, but be sure to cook the chicken fully before mixing it in the casserole to avoid undercooked meat and to ensure the right texture. Shredded rotisserie chicken is an easy shortcut that works perfectly.
Is there a way to make this recipe lighter?
Absolutely! Substitute Greek yogurt for the sour cream and use a low-fat cream of chicken soup. You can also opt for reduced-fat cheese, though the casserole will be a little less rich and creamy.
Can I make this casserole gluten-free?
Yes, just swap out the Ritz crackers for gluten-free cracker crumbs and ensure your cream of chicken soup is gluten-free. This way, you keep all the flavor and texture without the gluten.
What can I do if I don’t have Swiss cheese?
Gruyère or mozzarella are great substitutes if Swiss cheese isn’t on hand. They melt nicely and offer a similarly mild, nutty flavor to complement the ham and chicken.
How spicy is this Chicken Cordon Bleu Casserole Recipe?
This casserole has a mild flavor profile, with just a slight tang from the Dijon mustard. If you want to add a bit of heat, consider stirring in a pinch of cayenne pepper or serving it with a side of spicy mustard sauce.
